Make sure that your variable name for "Workspace" is not misspelled or you have used upper or lower case between the variable name and the inline substitution (i.e. "Workspace" versus "workspace"). A quick question as i'm not sure about your workflow in your model is, does your Geodatabase exist before the model is run? If the following doesn't help, I'd suggest you attach your model and sample data onto the following forum for the community to have a better look at to see why your model is failing. Regards ...

I've noticed that a very large amount of the geoprocessing tools found within the ArcToolbox doesn't effectively utilise the processor or memory within my PC. A simple task of projecting a point feature class only utilises 10% of the processor and 90 MB of memory. The process has been running for more than 10min just to project two feature classes. This is a common trend among all the Geoprocessing Tools found within ArcToolBox. The utilisation of PC resources needs to be drastically improved within ArcGIS and especially the Geoprocessing environment. The projection of the two feature classes took 1hr19min! Regards ...

Hi Mark 🙂 Thanks for replying to my post, yes I've set the Processing Extent under the Geoprocessing\Environment Settings, yet is seems the ArcHydro Tools doesn't adhere to the Environment Settings as it still processes the entire extent. I'm busy processing a very large study area and testing a new model that I've developed with ModelBuilder; HEC-GeoHMS and ArcHydro. I don't want to clip the DEM as this resamples the DEM and changes the cell values ever so slightly causes the results to differ from the full model. I was hoping to run the model based on a defined extent of the existing rasters without having to clip the rasters. Are you setting the processing extents via "Geoprocessing>Environments"? My practice has always been to extract by mask a rough cutout portion of the our countywide DEM before starting a ArcHydro project. I originally assumed I'd need to do this to limit the processing extents. All he ESRI examples do this. A second reason to extract the local DEM is to preserve the data set. The countywide data can be updated periodically. I'd like to preserve the dataset so that if the DEM changes, I can do a comparison to see if there will be different results in the future. So I've never run into your problem. I've had the batch processing run only for the batch point extents.  (http://forums.arcgis.com/threads/41988-Resetting-Raster-calculation-limits). This was before I knew about "Geoprocessing>Environments". So in my experience, I've had the opposite problem you are having. I't seems to only be happening with the ArcHydro tools within the Toolbox as my spatial analyst tools work correctly. Regards ... View more

Hi Stuart I uninstalled ArcHydro 2.1.0.30 and installed 2.1.0.98 successfully. Even if you dont dock ArcToolbox it still forces ArcCatalog to close and won't open thereafter unless I delete the Normal.gxt or remove HEC-GeoRAS. I've decided to work from ArcMap for now in order to complete my model for the ESRI UC. I'll see if Dean has some time after the Hydro Meet to have a look at why its not behaving. Thanks for your assistance, are you attending the UC this year? I did like to meet and exchange ideas. Peter, The installation log looked fine, just the usual MSI installer confusion over ROOTDRIVE and TARGETDIR pointing to another drive on the system H:\--non issues for the install, and the HECGeoHMS looks to have fully installed. Did you afterword go ahead and back out the ArcHydro Tools 2.1.0.30 and install the 2.1.0.98 build? Also, regards the ArcToolbox Window crash when docking in ArcCatalog, does it otherwise seem to behave when the Arc Toolbox window is allowed to float without docking? If it works, suggest you don't dock it. There have been past problems with objects of the Desktop 10.0 GUI associated with docking and undocking actions, most were supposedly taken care of at SP2. But suppose they could have resurfaced at SP5. Stuart Regards ... View more

Hi Stuart Thanks once again for trying to assist me with the following. I followed your recommended advice and after deleting the user account, deleting all ESRI Templates and deleting the current ESRI registry key. The AcrHydro Toolbox and HEC-GeoHMS Toolbox shows up within ArcToolbox, but ArcCatalog crashes as soon as I try to reopen it after docking the ArcToolbox. I've attached a print screen of the ESRI crash report as well as the Installation Log File Peter,  If installed from a command windows as per the example, the installation log (archydrotoolsInstall.log) would be in the same folder from where the installation package (ArcHydroTools.msi) was run.  However, it looks like something is wrong as your screen shot of your "Toolbox Window" does not show Arc Hydro Tools, yet its .tbx file is visible in your System Toolbox screen shot. I am pretty sure that when correctly registered the Arc Hydro Tools toolbox is treated as a "default" toolbox and should show.   On the other hand, the HEC GeoHMS Tools does not get picked up in the Toolbox Window--so it is not treated as a default toolbox and must be added. Adding it to the Toolbox Window should proceed without issue--as is visible in the attached screen clip where the GeoHMS Toolbox has been added.  So I suspect your installation did not run completely, as the screen capture of your Add Toolbox dialog does not show the GeoHMS Tools as present in the System Toolboxes object.  Have a look in the   C:\Program Files (x86)\ArcGIS\Desktop10.0\ArcToolbox\Toolboxes folder for the   GeoHMS Tools.tbx.   If not there, something went wrong with your installation and I'd look for problems with your installer privileges and reinstall.  If the toolbox file is present, then I would rename or delete your ArcGIS user profile (the files listed below) to allow default per user settings to be reestablished for your account on next launch and see if working with a default profile clears issue:  [INDENT]  C:\Users\<username>\AppData\Roaming\ESRI C:\Users\<username>\Documents\ArcGIS\Toolbox.tbx C:\Users\<username>\Documents\ArcGIS\Default.gdb **careful of deleting this one as you may have project data held there  and from a Registry edit session:  rename or delete the   HKEY_CURRENT_USER\Software\ESRI[/INDENT]  If the   GeoHMS Tools.tbx is not present in the Toolboxes folder, then the installation was flawed. Reviewing the log file may help you to identify the issue. One common problem for example would have been to run the installation as a non-priviledged user. The log should help identify that as well and I'd first check to be sure you've run the installation from a command window "Run as Administrator".  Stuart Hopefully you can spot something within the installation log file, its mostly gibberish to me.

Hi Stuart Thanks for getting back to me, as you have mentioned: Peter,  Not certain your issue will be the same as OP is having with HEC GeoRAS where language settings and out of cache conditions seem to be the problems. That said, I believe yours and others issues with the two HEC pacakges would be helped by the application of ArcGIS Desktopp 10.0 SP5 and shifting to current Desktop 10.0 build of ArcHydro Tools, i.e. 2.1.0.98  For HECGeoHMS issues, my understanding is that the USACE HEC asks Esri to limit the ArcHydro version to simplify their configuration management (and internal user support) of the HECGeoHMS package. If you choose to install HECGeoHMS, build 10.0.0.85, you are limited by its Microsoft installer packaging to install with the bundled version of ArcHydro, i.e. 2.1.0.30  As you found, if you already have an ArcHydro build installed, the HECGeoHMS installer will prompt you to uninstall it from the Add/Remove programs panel and then abort.  So, run the Add/Remove programs GUI (appwiz.cpl) and uninstall the "Arc Hydro Tools", or alternatively open a command window "Run as Administrator" and enter   msiexec.exe /x {777B898F-BB2C-4A7E-8FD9-A7E251C14E9D} This is one of the few instances that I would not aggressively clean-up the registry since you will be leaving ArcGIS Desktop 10.0 in place and will be reinstalling the version of ArcHydro Tools bundled with HECGeoHMS. If you want to be a bit more thorough about a full removal, you could download the ApRegWork utility from the ftp site and run ESRI.APWR.ApRegWork.exe and select only the "ARCHYDRO" search text.  With ArcGIS Desktop 10.0 intact, go ahead and run the HECGeoHMS installer. I prefer to run from a command window to be able to fully log the installation and to run the installation as Administrator, but you could simply select the installer and deal with UAC. The installer will now detect that no ArcHydro Tools are present and launch the installer for build 2.1.0.30, and then the HECGeoHMS installer, build 10.0.0.85--allow them to complete.  At this point I'd launch ArcMap and add both the "Arc Hydro Tools" toolbar and the "HEC-GeoHMS" to be sure they are functional then close them both, and close ArcMap.  Next use Add/Remove programs (appwiz.cpl) and uninstall the 2.1.0.30 version of "Arc Hydro Tools" as before.  Then download the current build of Arc Hydro Tools for Desktop 10.0, build 2.1.0.98 (2012-07-10) from the FTP site. Install that from command prompt "Run as Administrator" with   msiexec.exe /i ArcHydroTools.msi /L*v archydrotoolsInstall.log Could you assist me as to where do I find the installation log file?   Following the installation, review the log looking for any weirdness with installer variables--TARGETDIR, ROOTDIR, PYTHONHOME. And, if your Python26 installation was done outside of ArcGIS, you'll need to copy the   ArcHydroTools.pth file from   C:\Python26\ArcGIS10.0\Lib\site-packages to the correct Python Lib\site-packages location on your system. What I'm refereing to is if you add the HEC-GeoHMS toolbox from the Systems Toolbox to the ArcToolbox is crashes ArcCatalog and the only way of being able to re-open ArcCatalog successfully is by deleting the Normal.gxt file.   Then launch ArcMap and again add both the "Arc Hydro Tools" toolbar and the "HEC-GeoHMS" toolbar to check for function. Not guaranteed but that should have resolved the issues with your Adjoint Catchment. Regards your problems with ArcCatalog, not sure I follow your issue. I'm currently running ArcGIS 10 SP5 with Arc Hydro 2.1.0.98 and HEC-GeoHMS 10.0.0.85 on Windows 7 SP2   You don't add/customize the ArcCatalog toolbar. Rather, the Arc Hydro Tools and HEC GeoHMS and GeoRAS Tools should be accessed from the catalog tree view (ArcCatalog --> Windows --> Catalog Tree), but having the latest patches for the ArcHydro Tools and Desktop SP5 installed should help with stability I've attached a print screen, with regards to adding HEC-GeoHMS toolbox to ArcToolbox. Thanks for your assistance Stuart. Regards ... View more

Pleasure Fernando Thank you Peter! I've got some suggestions but I will try your schema, as it looks to be a simple and efficient way to do what I need. I'm glad your experience confirms that I'm not taking fool conclusions, but actually reaching the state of art limits. Thank you for sharing this with me, I appreciate that! Once I've completed my model, I'll post a copy of the model for you to have a look at. Regards ... View more

Dear Stuart I wanted to find out if you have used the latest version of HEC-GeoHMS 10.0.0.85. I previously had Arc Hydro 2.1.0.98 and had to uninstall it as HEC-GeoHMS 10.0.0.85 wants Arc Hydro 2.1.0.30. Once I had uninstalled Arc Hydro 2.1.0.98, I was able to install HEC-GeoHMS and ArcHydro. I've come accross two problems, the first is that if you add HEC-GeoHMS toolbox to ArcCatalog Toolbox it crashes ArcCatalog and the only way to get ArcCatalog to open without crashing is to delete the Normal.gxt. The second problem that I've found is that if you run Adjoint Catchment from the toolbox or within ModelBuilder the output is always empty. Just wondering if you have come across the following?
